One of the unexpected pleasures in playing God is when you discover two of your characters hate each other. It’s particularly satisfying when both characters are strong, articulate and quirky. My Grandmother character picks fights with one of her son-in-laws—a dentist. Their mutual animosity will have to culminate in something, or shift to alliance, or something, but for now, I’m having a blast engaging in snappy, cutting dialogue.
A peaceful troublemaker’s got to get her jollies somewhere, after all.
